I can tell you with a relative degree of certainty nothing will come out of this email. Not trying to disappoint you, but help you prepare. I know you feel there is a huge amount of important on this one email, and I wish you would not. It is an email, nothing more. Think of it as a single brick on a house. While you want it to be perfectly laid, if it is not you can always adjust down the road. What you should take from this is that your H is thinking of you. Whatever his motives may be, he is thinking of you. Believe me, he is going to think good things at times, and he is going to think bad things at times. Over time, the fabricated bad things will fade and what he will be remembering is the good stuff. Your job is to highlight the good things with your limited interactions. Sending him a happy email with enough mystery for him to wonder about what you are doing is a great way to start. It lets him know that your interactions will be positive, so he does not have to worry about arguing or meltdowns. For that reason, he will be more inclined to interact more. The fact that you give him something to wonder about plants the seeds of he may really lose you. And even if that is what he says he wants, he may not want that.
So keep your chin up and send your email. Then go back NC. It may be hours, it may be weeks till you hear from him again. Try not to focus on that. You sent a good email, now let him continue doing what he has to do.
